Is Trident the only render engine supported right now? I tried both WebKit and XULRunner and the IDE would not start with either of them selected. If they are supposed to work I will post the error detail here. Please let me know...

Thanks,

Dan

OKAY, HOLD THE PHONE: I found some stuff in the documentation about extra manual steps required to use either WebKit or XULRunner. Let me try those steps and see what happens. (grumble, grumble... *need a warning on the preferences page* ... grumble, grumble)

The team has spent countless hours deriving the list of supported browser configurations for EDT. The list of supported browsers, and how to configure them, can be found here - wiki.eclipse.org/EDT:Supported_Platforms

Thanks, Ben. I think the Help was spot-on where XULRunner is concerned but the steps for WebKit are better explained on the web. Since this does seem to be a pretty fluid topic (with considerations changing with each Eclipse variant) the web page reference is great idea.

The expertise required to set this up seems to be beyond my knowledge base. Would it be possible to get some clearer instructions on getting it to work with my configuration. Below is what I think one would need to know. However, I'm not sure.

Based on your response, I think I'm just confused. I would like to use the simplest, most straight forward method to try developing a test mobile app just to see how to do it. In my readings, I got the impression that I had to download Safari plus other things in order to do this. Since I'm still a novice at this, I may be just confused and need a helping hand to get out of my muck and back on the right track.

It is astonishingly complicated. I can't fault the EDT team though because they are just making use of what is supported by Eclipse. Without heavily customizing Eclipse itself I think they are pretty well stuck too.

Okay, so your goal is to try the mobile widgets ... that's good to know. The "setting up for mobile" part of that blog post is what you should follow:

I haven't tried it myself (as I say, my interest was in HTML5 and all I needed was XULRunner for canvas support). I'm going to try the mobile widgets now just for grins (which it appears does require Safari and a WebKit configuration).

I will follow up with my relative success or failure at this endeavor.

If you keep receiving below error:
"Error:
Internal Error
No more handles [Safari must be installed to use a SWT.WEBKIT-style Browser]
".

It is probably that xulrunner's settings has conflicts with webkit's settings.

Sometimes other eclipse based IDEs would set some global values to ensure SWT properly initialize a firefox browser during its installation, while it crashes webkit initialization. This is very annoying. To override the global settings, it might work if you add below configurations to EDT's eclipse.ini file and then restart it.
-Dorg.eclipse.swt.browser.DefaultType=webkit
-Dorg.eclipse.swt.browser.XULRunnerPath=D:\ //!important: specify a wrong directory to force SWT not use XULRunner which crashes webkit initialization

To reuse firefox as the rendering engine, just remove these two statements.

Besides, if you have ever manually installed XULRunner, navigate to the directory where XULRunner installed, and run below commands to uninstall it in the console, since it also crashes Webkit's initialization in eclipse.
xulrunner.exe --unregister-global

Hi
Yesterday I got this error "No more handles [Safari must be installed to use a SWT.WEBKIT-style Browser]" as mentioned by Smyle in previous post when running 8.1 32 bit and I tried the instructions from Smyle. This was not successful for me. The problem started after updating to Java 7.7, 32 bit (It was a recomandation even though I am running a 64 bit machine). After uninstalling Java 7.7 32 bit, keeping Java 7.7 64 bit, all seems to be working as normal again.
